The Nineteenth Workshop on Mobile Computing Systems and Applications (ACM HotMobile 2018) continues the series of highly selective, interactive workshops focused on mobile applications, systems, and environments, as well as their underlying state-of-the-art technologies. HotMobile's small workshop format makes it ideal for processing and discussing new directions or controversial approaches.

We solicit submissions of position papers that focus primarily on applications and systems and that propose new directions of research, advocate non-traditional approaches to old (or new) ideas, or generate controversy and discussion.
